Answer:
v = 5 m/s
Explanation:
Given that,
The distance covered by a runner, d = 400 m
Time, t = 80 sec
We need to find the runner's average speed. It is equal to total distance covered divided by time taken. It can be given by:

So, the runner’s average speed is 5 m/s.
Cerebellum... plus 20 characters to explain it well
It is the variable being controlled/changed to see if there are any effects on the dependent variable (the thing getting tested/measured)
The answer is D) Structural
That is because we can automatically cross A out, and B is not the answer because ionic compounds aren't polyatomic. Poly atomic atoms are covalent and have no charge. While on the other hand, ions have a charge.
Also, C is not the answer because the molecular formula for glucose is <span>C6H12O6, that leaves us with choice D.

I can pretty much conclude that D is the answer because you can see that the picture, it has a structure for the compound. Its showing us how the atoms are bonded and structured.
